Airtac TMIC Guided Cylinder with Guide Unit TMICM20X150
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM20X150 is a genuine guide-frame (guided) pneumatic cylinder — a Ø20mm double-acting MI mini cylinder built into a twin-rod guide unit running on brass bearings. The guide frame absorbs side load and torque so the 150mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICM20X150
Built around a 20 mm bore twin-rod aluminium guide frame running on brass bearings, this double-acting guided cylinder integrates a variable air cushion at both ends to absorb high-speed end-of-stroke shock. The brass bearing design provides high torsional stiffness and strong radial-load resistance, making it the right choice when the tooling twists or pushes sideways. With a 150 mm stroke and an 8 mm rod, it uses a 1/8" port and delivers 157 N of push force at 0.5 MPa.
Because the frame carries the side load, the thrust is not the guided-load limit; you must size the allowable payload from the TMI/TMIC load-offset curve. For a practical setup, a safe working thrust is roughly 94 N (about 60% of the 0.5 MPa push force), which translates to pushing about 8 kg vertically with a 2:1 safety margin, load curve permitting. Note that this specific SKU lacks a magnet and cannot accept CMSG, DMSG, or EMSG sensors.

Specifications follow the official AirTAC TMI/TMIC datasheet. Guide frame & fixed plate: aluminum alloy; matching cylinder: MI/MIC round-body mini cylinder. Allowable load depends on the load-offset distance — consult the TMI/TMIC maximum-load curves before final selection. Thread options: PT (blank) / G.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 kgf | |
Thrust equals the underlying MI cylinder. The usable load a guide frame can carry is limited by the load-offset curve, not by thrust alone — always check both. Actual force is lower than theoretical due to friction and back-pressure.

Where the Airtac TMIC Guided Cylinder with Guide Unit TMICM20X150 Is Used
High-Speed Package Diverting
Uses the 157 N push force to swiftly deflect parcels on a sorting line, while the brass bearings resist the torsional twist of side-mounted paddles.
Automated Drilling Head
Plunges a light spindle over 150 mm; the twin-rod frame keeps the bit square, and the variable air cushion prevents bounce at stroke end.
Vertical Lift Gate
Raises an 8 kg access panel with a 2:1 safety margin, relying on the guide frame to handle the off-center load without binding.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM20X150 the Right Cylinder?
When sizing this 20 mm bore unit, consider stepping down to a TMICM16X150 for lighter duty (100.5 N push at 0.5 MPa) or up to a TMICM25X150 for heavier loads (245.3 N push at 0.5 MPa). Choose this brass-bearing M variant over the linear-bearing TMICL when your application involves high torsional loads or sideways pressure rather than pure low-friction precision. The needle-set variable air cushion is essential for high-speed travel over the 150 mm stroke, preventing harsh impacts at the ends.
Always verify the maximum payload against the load-offset curve, as allowable weight drops significantly the further the load sits from the guide plate. This non-magnet SKU cannot support position sensing; if you need CMSG, DMSG, or EMSG switches, select the -S variant. Remember that the cushion only decelerates the piston near stroke end and does not lock the load—if air pressure is lost, the rod will drift, requiring an external pilot check valve or rod lock for holding.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Keep the load within the load-offset curve.
- check Mount on a flat, rigid surface using the fixed plate.
- check Do not exceed the rated speed (30-500 mm/s).
- check Installation by qualified personnel per AirTAC docs.
Airtac TMIC Guided Cylinder with Guide Unit TMICM20X150 FAQ
This 20 mm bore cylinder provides 157 N push and 131.9 N pull at 0.5 MPa, and 219.8 N push at 0.7 MPa, with a theoretical max of 32 kgf at 1.0 MPa. However, thrust is not the load limit; the actual payload it can carry depends entirely on the load-offset distance and must be verified using the TMI/TMIC maximum-load curves.
This specific SKU does not have a magnet and cannot accept CMSG, DMSG, or EMSG sensors; you must order the -S variant for switch readiness. It uses brass bearings for high torsional stiffness against sideways loads, and a needle-set variable air cushion at both ends to decelerate motion smoothly without acting as a lock.
